Why does my phone snap a picture when I delete recent calls from my call log?

Hi Freckleface77,

Are you referring to taking a screenshot? If so, when deleting recent calls are you holding your iPhone in a way that would allow for a screenshot to take place? The steps below found in the article here can help you check. Take a screenshot on your iPhone

"How to take a screenshot on iPhone 14 and other models with Face ID

1. Press the side button and the volume up button at the same time.
2. 
3. Quickly release both buttons.
4. After you take a screenshot, a thumbnail temporarily appears in the lower-left corner of your screen. Tap the thumbnail to open it or swipe left to dismiss it."

If that's not the issue check to see if you have "Use Volume Up for Burst" turned on with the help of the guide here: Capture action shots with Burst mode on your iPhone camera - Apple Support

Best.
